I am using WP 2.8.4. and Atahualpa WP Theme version 3.4.2. Previously I was working on my site behind a URL e.g. www.wordpress.org/hiddenfolder/ . When i was through building my site i put it in the right folder and in this case it would be www.wordpress.org/
I made sure I edited the URL in the DB to point to the correct folder but now the images cache is still pointing to the old URL.
Kindly advice how to clear it.
